WHEEL-TIRE fipecification of Letters Patent.

Patented March 9, 1909.

Application filed. November 12, 1907. Serial No. 401,841).

To all whom it may concern:

Be it known that I, Janus Ci-nns'rr, a citizen of the United States,residing at Akron,

and State of Ohio,

and useful ill!- of which the in the county of Summit have inventedcertain new provements in Wheel-Tires, following is a specification.

This invention relates to fastening devices for pneumatic or othersimilar tires, and has for its object to. provide an-improvedconstruction which will permit the tire and rim to be placed or removeda whole, without deflating the tire or detacln ing the same from therim.

The invention will be found. particularly useful in connection withautomobiles, ti 7 intent being to carry an extra tireand rim. with thetire inflated, so that in case of puncture of one of the tires. it canbe removed and the extra tire substituted with a delay out a few minutesonly.

lit-"further object of the invention to provide improved means forholding the reaming rings, which engage the base oi and in such mannerthat they can be quickly removed if and when desired.

The invention is illustrated in the accompanying drawings, in whichFigure 1 is a sectional view showing the F g. 2 is a side elevation of aportion Fig. 3 is a sectional view of a Fig. l. is a longitudinal secot'attaching the split retaining ring to the rim and fastening the sametogether. f'i 5 is a sectional view ot' another modification.

Referring specifically to tire. thereof. n'mdilicution. iion showii'igthe nuumer the drawings, the

telly ot' the wheel is indicated at 6 and has thereon an inner band orrim 7. This may be bolted on. the telly or fastened thereto in any othersuitable manner. At one edge it projects"inter-a1ly"hcyon(l the side oi:the telly, and has a downwardly or inwardly It i 1- 0 (r o 71 wt i" i oi ccnum an e J u um c. runs a ...n angu. to and is spaced iron) the sideof the folly.

This rim is conn urativoly pernn ncnt and is intended to remain on thetelly.

10 indicates an outer or secondary rim which is of proper size anddiameter to fitover the inner rim 7, at a snug fit. It has at one edgean outwardly extending flange 11, and at the other edge it has aninclined inwardly extending flange 12 which fits snugly against theflange 9. At the outer edge of the flange 12 is an upturned lipli'l,forming the flange 12, and

said groove forms a seatof the retaining ring 1 1. Said retaining ringis splitand scarfed at one place, .as shown at 15, and. is of propersize to extend around and rest upon the lip, lying with its side againstthe flange 12. When the ends of the ring are drawn together its inneredge fits within the groove behind the lip 13, which thus holds the ringin place. One end of the ring 14: is attached to the adjacent flange ofthe rim by lug 16, and the other end is held by abolt 17 through thering and through the flange oi the rim. Instead of the bolt 17 a screwmay he used as shown in Fig. t. The bolt or screw extends through theflange of one or both rims, according to whether one rim is used, inFig. 3, or the double rim, as in Fig. 1.

- The flanges of the tire opposite sides by hooked rings 18,

base are engaged on in a manner common with clencher tires, and theserings are rabbeted at their inner edges, as indicated at 19. On one sidethe rabbet {its over or receives the flange 11 on the rim, and on theother side the rabbet receives the outer edge of the retaining ring 1which thus holds the parts in place and retains the tire 20 on the rim.

In Fig. 1 the inner and outer or double rim is shown, as abovedescribed, and'with this construction, by ren'ioving the not on the bolt17 the outer rim 10 and the tire secured thereto may be bodilydismounted or removed from the wheel, without deflating the tire. Andobviously another rim and tire can be as readily substituted. This willallow a very quick change when desired, and it is necessary to loosenonly one bolt. However, additional bolts may be provided around the ringif desired or found to be necessary.

In Fig. 3 the simple or single form' is shown, the inner rim 7 beingomitted and the other parts being similar in all respects to the partsabove described. This lacks the feature of permitting the rim and tireto be dismounted without deflation, but includes the retaining devicesat the edge of the rim.

In Fig. 5 a modification is shown having a standard or known one-piececlencher rim 21 fitting over an inner rim 22 which is bolted to thetelly and which has at one edge a flange 23 projecting outwardly againstthe outer rim and at the other edge a. flange 24 which extendsprojecting inwardly and supporting a retaining ring 25in a mannersimilar to that described above, except that the retaining ring does notproject into a groove or rabbet in the outer rim, but bears against thesame, in such manner, however, that the outer rim is retained in placeon the inner rim, and can be slipped off laterally by removing theretaining ring 25 in the same manner as above indicated with respect tothe ring 14.

The invention is capable of modification Within the following claims andis therefore not limited to the exact forms shown.

ll claim:

1. The combination of a Wheel rim having a flat flange at one edgeprojecting inwardly at an inclination, with a lip at the edge'of'said'flange, a removable ring resting, upon the rim and engageable withthe base of a tire, a split retaining ring fitting around the lip andresting at an inclination against the flange, and fastenings securingtheends of the retaining ring to the flange.

2. The combination of a felly, a fixed inner rim thereon having aninwardly projecting flange at one edge spaced from the side of thefelly, a removable outer rim fitting over the innerrim, and having anoutwardly projecting flange atone edge and an inwardly projecting flangeat the other edge provided with an outwardly projecting inwardlyinclined flange at one edge and, a.

lip atthe edge of said flange forming an outwardly presented angulargroove, a removable ring mounted upon the sald rim 'and adapted toengage the base of a tire, a

split flat retaining ring having a corner fitting in said groove andinclined inwardly against the flange, and having lapped ends, andfastenings between'the ends of the ring and the flange.

In testimony whereof I affix my signature, in presence of two witnesses,

W. F. BOWEN, M. E. Ronnn'rs.
